Question: In my anamoly scan , it shows prominent bilateral fetal renal pelvis with AP diameter of 3.8mm (right) and 4.7 mm (left) is given.what does it mean, is it a thing to worry

Answer: Mild dilatation is acceptable, Can be due to the obstruction in the flow of urine It resolve on its own over time You should correlate it with NT scan double marker or triple marker screen test, if this is the Single abnormality seen then no need to worry about Only thing you need to do is repeat ultrasounds with measurement of kidney should be done to see whether it is increasing or decreasing Baby will be monitored till 1 month after delivery.

Answer: Renal pelvis dilatation (or hydronephrosis) is a widening of the renal pelvis and is a common finding on ultrasound scans (USS) performed during pregnancy. Often it is temporary and not associated with any problems in the kidney or ureter.The measurement from 'front to back' of the renal pelvis is measured at your 20 week ultrasound scan. The normal measurement of the renal pelvis is 0-7mm before 24 weeks and less than 10mm after 28 weeks. If the measurement is more than this, it is called renal pelvic dilatation.

Answer: No don't worry. See in next scan also if it is increasing. Also do a scan after baby is born to check the exact size.
